l To' @Erw/tom. it may concern:

of a switch stand having a novel leverv mechanism for. .operating thetarget and switch rod. ,L

Another Objectis to provide a switch stand having means tor locking theinternal mechanism against movement whenv the-- \switch/ is accidentallytrailed.v

.A urtherobject is to provide a switch f and durable. i

The above and other objects and ativantages will be brought out in thefollowing specification and illustrated in the accompanying drawings, inwhich--l Figure 1 ,is .a top planet a. switch stand constructedinaccordance with. our invention.

Figure 2Ai's a side elevation of the same.

Figure 3 is a top plan ofthe stand with' the top of the casing'removedto show the internal mechanism of the stand. i

Figure 1 is asectional elevation ofthe stand developed substantially onthe irregular line tV-'IV of Figure 3.

Figure 5 is an elevation or" the assembled upper and lower spindlesforming the target shaft and the spindle arm.

Figure 6 is a detail perspective -view of the lowerspindle. L Figure 7is a detail perspective view of the upper spindle.

Figure 8 is a detail perspective view of the spindle arm.

Figures 9 and 10 a're detail perspective views of the adjustable wedgesfor the lower spindle. u

Figure 11 is a plan of the hand operating lever and crank arm.

Figure 12 is av fragmentary detail elevation of the connecting jaw ofthe operating crank arm. j y

Referring more particularly to the drawings, the letter A designates thecasingfof the stand as a whole, which is composed or' upper and lowersections 2 and 3 which are open at `one side formmga doorway whichSTAND.

is closed by a4 door 4. The lower-section ot the casing isv provided atdiametrically opposite sides with the usual feet 5 for securing thestand to a suitable. base.

The upper and lower sections 2 and 3 are provided with vertically alinedbearing apertures inwhich the ends ot'a vertical shaft composed of upperand lower spindles 6 and 7, respectively, are journaled. The spindle 7is provided with a recess" or socket 3 in which the lower end 9 of thespindle 6 is Journaled. The spindles cooperate to form what isordinarily termed the target sha'ft. of the standar-id theupper end otheupper spindle projects'-beyond the casing and carries -a targetfl'O,.while'the lowerend ot the spindle 7 projects .through the casing andhas a. crank arm 1 1 secured thereon by a breakable collar 12 which ispinned on the lowerend of the spindle 7. The breakable collar 12 isprovided with a pair of lugs 13 either ot which is adapted to titbetweena p air of ears 14 on the crank arm 11. Theretore, if the switch isaccidentally trailed the shock will break the lug 13 engaged between theears 14 on the crank and release said crankl so that it may turn freelyon the spindle '7, thus preventing the damaging ot any of the internalmechanism of the stand. It one of the lugs 13 is broken, the collar maybe reversed and the other lug engaged between the ears 14.

A switch rod link 15 is pivotally secured. to the crank arm 11 andadapted to`be connectedl to a switch rod, .(not shown).

The .lower spindle 7 is provided with a slotted arm 16 having serrations17 on its side .faces A pair of 'adjustable wedge members 18. and 19 aremounted onthe opposite sides of the arm 1G Aand comprise a curved orrounded wedging head Qllyaiid an apertured body portion 21. The innerfaces of head 2O and body portion 21 are on the same plane and areprovided with serrations 22 adapted" to mesh with the s errations 1'! onthe side Jfaces of the arm 16:

The upper end or head 20 of the members 18 and 19 projects at rightangles over the arm 16 to form a support, and the members are secured orlocked in position on the arm by a bolt 23 which passes through theapertures in the body portion 21 of the wedges and through the slottedbody of the arm 16.

The upper spindlehas an enlarged body portion 25 provided with an archedaperture 26, bearing'ortices 27," and projecting jaws ico \ 8. The wings28 are spaced apart cve their inner surfaces Iinclined or "1 so as to'form a bearing me wedges 18 end 19; That is, engage the wedges 18end-19 "Jer spindle is rotated,"t he -inoi the' wings ride on' and bearQfaedges so as to orcethe lower yrotate, thus moving the crank arm il.endAoperatin-g theswitch. 1

lt wiil be noted that the wedges 18 and 19 ere'edjnstebly secured to thearm; 16 and may' be, adjusted.. longitudinally thereof. .lhererpere, ifthe wedges 18 and 19 be movedy erdly or tof/verd' the Afree end ci. theerm16,the upper spindle will be, 'permitted "in amount-of free movementbefore ws contact with the wedges: lo e r spindle o is adapted to be ro;by a toggle like connection, which ce mprises.e` spindle arm or lever29,' a crank erm 3U., operating lever 31.

' The spindle arm. 29 has .an apertured c, e, i L

po ion 32 journaled on a pin 33 fl- :in the bearing orrces of thespindle, a shank portion 34, and a portion. 35.' i

y logportion 85 oi' the' spindle arm ed to be engaged in an open sidedyolre 36 on the end of the crank m 3G, which arm is onrnaledin avbearing [fin with counterweight 39. les the 1 is lifted and swlmg to thelesite ide o the casing', it willrotate the i520 in the bearing 37, thusraising ce rocking the crank en/ d of the arm and spindle 'in thedirection the lever 31 is sivo-ng. That is, as' the crank arm 30-isrotate-d, the crank end will move upwardly and sidewerdly so as to rockthe-spindle' erm 29 about the pin 5,3 and rotate the upf per spindle 6.The rotating movement of the ripper spindle o -will be communicated'.through the jews or wings 28 and wedges 18 and 19 to the lower spindle,thus rotatinglower spindlef and operating the crank' yarmll and switchrod linll. which is conne'cted. to theswitc'h rod.

As hasjbeen sta-ted, the vwedges 18 and 19 are ediustelclyv mounted onthe arm 16 and may be moved toward or away'from the 28 oi 'the upperspindle to very the free movement of the operating mechanism the stand.That. is, if the wedges 18 and 19 moved a predetermined distance ewayfrom the jaws or wings 28 the upper spindle 6, spindle erm 29, crank arm30, and `lef-.fer 51 may be moveda predetermined dis- -e the wingsengage the wedffee 1S the switch. The preierred 18 and 1i? 'will be edin thecasing of the Stand. The

that which will permit the `lever 31 to' be moved upwardly .toitsvertical position be-. forethe wings 28 enga-'ge the vfedges.-

The spindle erm' 29 is providedwith lugs l() projecting from each sideof the shank portion 3 4 and ends of an upwardly projectingL lug-4 1'onthe lower sectionothe casing, thus-preventing thev movement ci .thespindles-when thei'switch is accidentally trailed or other-wise forced..rllie weakest connection in the whole train of mechanism is the' lug 13onthe collar 12. Thereorefi" the switch'is .trailed this lug will breakand the remainder of the mechanism will be un injured.
